The question is incomplete. Here is the complete question:
The following annual returns for Stock E are projected over the next year for three possible states of the economy. What is the stock’s expected return and standard deviation of returns? E(R) = 8.5% ; σ = 22.70%; mean = $7.50; standard deviation = $2.50
State Prob E(R)
Boom 10% 40%
Normal 60% 20%
Recession
30% - 25%
Answer:
The expected return of the stock E(R) is 8.5%.
The standard deviation of the returns is 22.7%
Explanation:
<u>Expected return</u>
The expected return of the stock can be calculated by multiplying the stock's expected return E(R) in each state of economy by the probability of that state.
The expected return E(R) = (0.4 * 0.1) + (0.2 * 0.6) + (-0.25 * 0.3)
The expected return E(R) = 0.04 + 0.12 -0.075 = 0.085 or 8.5%
<u>Standard Deviation of returns</u>
The standard deviation is a measure of total risk. It measures the volatility of the stock's expected return. The standard deviation (SD) of a stock's return can be calculated by using the following formula:
SD = √(rA - E(R))² * (pA) + (rB - E(R))² * (pB) + ... + (rN - E(R))² * (pN)
Where,
- rA, rB to rN is the return under event A, B to N.
- pA, pB to pN is the probability of these events to occur
- E(R) is the expected return of the stock
Here, the events are the state of economy.
So, SD = √(0.4 - 0.085)² * (0.1) + (0.2 - 0.085)² * (0.6) + (-0.25 - 0.085)² * (0.3)
SD = 0.22699 or 22.699% rounded off to 22.70%
Answer:
Serendipity
Explanation:
From the question we are informed about Larry, who is the owner of small hotel resort, would like to advertise his hotel in major American newspapers and magazines as a part of his larger strategy. However, he doesn't have enough money to do so. One day, he meets Todd, the owner of a group of newspapers and magazines, who offers him advertising space in his publications on the condition that Larry provides him with a free stay at the hotel. This is an example of Serendipity.
Serendipity can be regarded as unplanned fortunate discovery, which is a common occurrence that could take place throughout the history of a particular product invention as well as scientific discovery. It can be explained as the luck that comes to some people way as they are finding or creation of interesting things as well as valuable things by chance
it depends what it is for
Partner Airline
Partnerships between or among airlines are known as airline alliances. Through these partnerships, airlines can pool resources, add or expand partner routes, and even provide the opportunity for customers to accrue and redeem miles through one another's rewards systems.

For the spring of 2020, I'm looking into multi-city flights from Seattle to Rome and Rome to Seattle. On Lufthansa, premium economy is not an option for the dates I'm considering. However, I can discover routes flown by Lufthansa on the United website and have the option of choosing premium economy. However, I am unable to choose seats on the United website. It informs me "On this flight, there are no available advance seat assignments on united.com. You can go to the operating airline's website for more information after completing your purchase." I am less than certain that we will truly enter premium economy and may instead wind up in ordinary economy as a result of this. Please share your insights into this kind of reservation! Thanks!
